and redo the same operation as show in the section :dump the kernel in
freebsd developer handbook :

On panic :
Fatal trap 12: page fault while in kernel mode

fault code              = supervisor read, page not present
instruction pointer     = 0x8:0xc16497e8
stack pointer           = 0x10:0xc80fed1c
frame pointer           = 0x10:0xc80fed20

                        = DPL 0, pres 1, def32 1, gran 1
processor eflags        = interrupt enabled, IOPL = 0
current process         = 518 (beautiful)
